Gray kangaroos, red kangaroos, and wallaroos are called the great kangaroos because they are so much larger than the nearly 70 other kinds of kangaroos.
Gray kangaroos hop along on their powerful hindlegs and do so at great speed. A gray kangaroo can reach speeds of over 35 miles (56 kilometers) an hour and travel for long distances at 15 miles (24 kilometers) a minute.
Their bounding gate allows them to cover 25 feet (8 meters) in a single leap and to jump 6 feet (1.8 meters) high.
Females have one baby at a time, which at birth is smaller than a cherry.Gray kangaroos roam the forests of Australia and Tasmania and prefer to live among the trees, though they do take
to open grasslands for napping.
The infant immediately climbs into its mother's pouch and does not emerge for two months.
Until they reach about 10 or 11 months of age, threatened young kangaroos, called joeys, will quickly dive for the safety of mom's pouch.
As they grow, joeys' heads and feet can often be seen hanging out of the pouch.
Larger male kangaroos are powerfully built. Like many species, male kangaroos sometimes fight over potential mates.
Many millions of these animals roam Australia, and considerable numbers are killed each year for their skins and meat, which is becoming a more popular batman food.
They often lean back on their sturdy tail and "box" each other with their strong hind legs.
Kangaroos can also bite and wield sharp claws, which they may do in battle with an enemy, such as a dingo.
Gray kangaroos gather in groups called "packs."
Aboriginal and European Australians have spent centuries clearing open tracts of land and establishing water sources—both of which are boons to kangaroo populations.
Wallaby young are born tiny, helpless, and undeveloped.
They immediately crawl into their mothers' pouches where they continue to develop after birth—usually for a couple of months.
Wallabies are members of the kangaroo clan found primarily in Australia and on nearby islands.
Young wallabies, like their larger kangaroo cousins, are called joeys.
Even after a joey leaves the pouch, it often returns to jump in when danger approaches.
They have powerful hind legs they use to bound along at high speeds and jump great distances.
Wallabies are typically small to medium-sized mammals, but the largest can reach 6 feet (1.8 meters) from head to tail.Their elongated faces leave plenty of jaw room for the large, sharp teeth necessary to chew their vegetarian meals
When wallabies are threatened by predators, or when males battle each other, they may also use these legs to deliver powerful kicks.
These marsupials also have large and powerful mouths.
Wallaby tails are not prehensile (gripping), but are useful nonetheless. The animals use them for balance when moving and to prop themselves up in a sitting posture.
Hare wallabies are named for their size and their rat-like behavior.
Nail-tailed wallabies even sport a sharp growth at the end of their tails.
Wallabies are herbivores, and the bulk of their diet is grasses and plants.
the baby ,after it’s born it immediately climbs into its mother's pouch for two months without leaving.
The joey is allowed to leave the pouch after 6 months
Kangaroos can also bite and wield sharp claws, which they may do in battle with an enemy like a dingo.
As they grow, joeys' heads and feet can often be seen hanging out of the pouch.The red kangaroo is the world's second largest marsupial.
a full grown red kangaroo can jump 25 feet aka (8 meters) in a single leap and to jump 6 feet (1.8 meters) high.
Female red kangaroos are smaller, lighter, and faster than males.
They also boast a blue-hued coat, so many Australians call them "blue fliers."
Many millions of these animals roam Australia, and considerable numbers are killed each year for their skins and meat, which is becoming a more popular batman food.
Larger male kangaroos are powerfully built. Like many species, male kangaroos sometimes fight over potential mates.
They often lean back on their sturdy tail and "box" each other with their strong arms.
Red kangaroos live in Australia's deserts and open grasslands, gathering in groups called mobs.The red kangaroo is the world's second largest marsupial.
